Pasinei nemwaka, masupamaketi uye misika yevhiki nevhiki inopa mastrawberries matsva, mabhanana nemadomasi gore rose. Zvakaipa zvakadii kune zvakatipoteredza kudya michero nemiriwo mitsva munguva yechando? Tinotsanangura kwaunogona kusvika uine hana yakanaka.
Huyero hwemamiriro ekunze uye mamiriro ekunze echikafu kubva musupermarket zvinoenderana pamusoro pezvese kuti zvigadzirwa zvakarimwa sei, zvakatakurwa nekuiswa pakiti.
Kana iwe uchida kudya zvakagadzikana, iwe unofanirwawo kuterera kune yemvura tsoka.
Zano: Enda kunotenga nebhasikoro kana netsoka pane kutyaira - izvi zvinochengetedza huwandu hwakawanda hweCO2.
Fresh sitirobheri, raspberries uye blueberries, maapuro uye matomatisi? Izvi zvagara zviri zvakajairika mumadhipatimendi emichero nemiriwo emasupamaketi gore rose - uye hazvimire pazvitoro zvikuru. Asi vatengi vakawanda vari kuzvibvunza mubvunzo pavanenge vachizvitenga: Izvo zvakanakawo kune zvakatipoteredza uye mamiriro ekunze?
Nezve carbon footprint yemuchero mutsva nemiriwo
Chinhu chimwe chakajeka: kana tomate nemastrawberries zvichibva kuGermany kana kuEurope munguva yechando, zvinenge zvichipisa mugreenhouse, iyo inopedza simba rakawanda, kana kuti yakatakurwa madaro marefu. Asi zvakadini nemichero yokune dzimwe nyika yakadai semapanapple, mabhanana, mango, maranjisi nemaavocado, ayo anogara achibva kure chero nguva ipi zvayo yegore?
Vatsvagiri kubva kuHeidelberg Institute for Energy and Environmental Research (Ifeu) vakaongorora mubvunzo uyu uye vakawana mhinduro dzinoshamisa. “Nezvekudya zvinobva musupamaketi, kuenzana kwemhoteredzo nemamiriro ekunze kunowanzotsamira zvishoma pachigadzirwa chacho uye zvakawanda pamusoro pokuti zvinhu izvi zvakarimwa kupi, kutakurwa uye kuputirwa sei,” anodaro Dr. Guido Reinhardt, uyo akatungamirira chidzidzo cheEcological Footprints of Food and Dishes. muGermany.
Ndezvipi zvinhu zvinonyanya kukosha?
Izvi zvinoreva kuti: kana chinanazi kana apuro rakanganisa kana kuchengetedza mamiriro ekunze zvinoenderana nezvikonzero zvakati:
- Goho panharaunda
- Kurimwa pane yaimbova ivhu rakasikwa uye rinokosha
- rudzi rwekurongedza
- nzira yekufambisa
Nzira dzekufambisa dzinoita basa guru pamamiriro ekunze
Semuenzaniso, chinanazi chinouya kuGermany nechikepe chiri nani kumamiriro ekunze zvakapetwa ka25 pane chinanazi nendege - uye richiri nani zvakapetwa katatu pane mananasi omumagaba. Maapuro emudunhu nemwaka pamwe nemaapuro ekuchengetera kubva kuGermany anoenderana nemamiriro ekunze zvakapetwa kaviri semaapuro anobva kuNew Zealand. Uye izvo zvisinei negoho rakanyanya kukwira panharaunda paNew Zealand maapuro minda.
Exotic michero zvakare inofananidzwa nemamiriro ekunze kana makambani akasatakura nendege. Semuenzaniso, maapuro edunhu nemaorenji ane anenge akafanana kabhoni tsoka. Uye mapineapple nemabhanana anotumirwa anongoburitsa gasi rinokuvadza zvakapetwa kaviri pakirogiramu semaapuro edunhu mumwaka.
Zvikasadaro, zvinokoshawo kuti inzvimbo dzipi dzinorimwa michero nemiriwo: Masango anogara achinaya mvura akachekwa kuti arimwe here kana kuti ivhu rakachinjwa kuva ivhu rinorimika? Zvinhu zvakadaro zvinowedzera mamiriro ekunze zvakanyanya.
Iwe unofanirwa kudzivisa michero kubva munzvimbo idzi
Kana iwe uchida kudya zvine mwero, haufanirwe kungotarisa iyo CO2 tsoka. Pamusoro pemagasi egreenhouse, mamwe maitiro anoitawo basa. Semuenzaniso, kuwanikwa kwemvura. Zvibereko zvinobva kunyika dzisina mvura saka zvinonetsa. Izvi ndizvo, semuenzaniso, ne:
- Almonds kubva kuCalifornia
- Nhungirwa nebhinzi kubva kuEgypt
- Kiwi uye Oranges kubva kuIsrael
- Zvibereko nemiriwo kubva kuAndalusia neMorocco
Zvibereko zvinobva kumatunhu akadaro zvine mwero wakakwirira wemvura. Naizvozvo vatengi vanofanira kuzvibvisa zviri nani mukudya kwavo. Uye - nekuda kwemamiriro ekunze uye nharaunda - pachinzvimbo chekupa michero nemiriwo kubva mudunhu, mwaka uye zvakare kubva mukurima organic.
Ichokwadi kuti kurima organic kunoburitsa yakawanda CO2 nekuda kwegoho rakaderera pane imwe nzvimbo. Kune rumwe rutivi, zvisinei, inobatsira kumvura yakanaka yekunwa uye kunaka kwevhu uye kuchengetedzwa kwenyuchi.
Chekupedzisira asi chisiri chiduku, chimwe chinhu chinokosha kuti uchengetedze mamiriro ekunze ako pachako, anodaro Guido Reinhardt: “Tenga nebhasikoro kana netsoka panzvimbo pokutyaira uchienda kuchitoro chepurazi kana kumusika wevhiki nevhiki uchitenga kirogiramu yemaapuro necauliflower.” Izvi zvinoreva kuti vatengi vaizoparadza zviri nyore iyo CO2 yakachengetwa kana uchitenga.
